摘要:
Described are conduction cardiomyocyte-enriched cellular populations, and methods and materials for obtaining the same. The populations may be used to engraft mammalian myocardial tissue, for example to provide biological pacemakers. Also described are restorative cellular myocardial tissue, for example to provide biological pacemakers. Also described are restorative cellular myocardial grafts for improving the contractile function of injured segments of myocardium, and articles adapted for heart implantation (e.g. conductive pacemaker leads), which includes coatings of viable cardiomyocytes and optionally a carrier for the cardiomyocytes.
摘要:
Described are methods in vitro and in vivo which involve the use of increased cyclin D2 activity to activate the cell cycle of cardiomyocytes as a baseline measure and/or in response to stimuli. Also described are vectors useful for these purposes, and cardiomyocyte cells exhibiting an activated cell cycle. Transgenic cyclin D2 animal models are also described.
